Cisco MeetingPlace hotfixes and patches are now distributed through a Hotfix/Patch Installation Package format with a lightweight installer.
The Patch Installation Package is provided in a gzip file with this filename pattern:
MP<major_release_number><maintenance_release_number>_<hotfix_number>_<component_name>_<full_version_number>.bin.gz where:

major_release_number --- The major version of the software (for example, 8.5, 8.0, 7.1 shown without dot).

component_name --- Name of the component: APP, Multinode(ConfMgr, Admin, bcl, and other Java components). Applicable for Audio Only deployments and Outlook component.

full_version_number --- Full version number without dots (8.5.4.19).

Example: MP85MR2_HF2_MultiNode_85419.bin.gz

Patches and Hotfixes are developed on top of a full installation version.

The Patch/Hotfix Installation Package is cumulative. For example, HF3 package contains all the fixes included in HF1 and HF2, as well as new fixes in HF3. In order to ensure the stability and consistency of the overall installation, installing patch/hotfix with, for example, number 5, causes all earlier patches/hotfixes (from 1 to 5) to be installed.

Installation instructions

Please review Readme file which is distributed with every Patch/Hotfix release for general instructions.
